Microwave-assisted synthesis and characterization of tin oxide nanoparticles

Abstract Tin oxide nanoplatelets (SnO) and nanoparticles (SnO 2 ) were prepared by microwave assisted technique with an operating frequency of 2.45 GHz. This technique permits to produce gram quantity of homogeneous nanoparticles in just 10 min. The crystalline size was evaluated from XRD and found to range from 26 to 34 nm. SEM and TEM analyses showed that the nanoparticles present a platelet-like shaped particle or, a pseudo spherical morphology, after calcination at moderate temperature during which the phase transformation from SnO to SnO 2 takes place. Additional FT-IR, density and resistivity measurements were also presented.
